Home Sick Home Nine unleashes Grim Big on the Resistance, who are easily overwhelmed as he creates more Grimions. Sonic is cornered and pushed into a chasm, only to be saved by Shadow. With Shadow joining the fight, Sonic continues providing assistance, but Grim Big attacks with devastating firepower. After Nine loses more Grimions to Mr. Dr. Eggman's mothership, Grim Big attacks it and disables its lasers. The Roses and Dr. Done-It cover aerial support while Mr. Dr. Eggman repairs the laser cannons. Nine notices the scavengers coming and siphons more Prism energy to stop them, weakening Grim Big and the other robots. However, before Grim Big can attack again, the cannons destroy it.
